Go offline in Origin, close origin, disconnect from internet, then try installing. You will be asked for username and password. Origin must be installed and updated beforehand obviously, and previous download files removed. Worked for me at least.
- close Origin completely.
- Disable your internet connection. (Pull the plug or disable the Network adapters)
- Start Origin > login > Game Library > click "Download". (Origin should start installing from the disk.)
Do you have a Antivirus program that blocks access to your optical drive?
Did you tried to install directly from the setup.exe on the disk?
